I really want to have a couple of mommas because I want a continual meat supply as well as eggs. If I purchase a full grown hen and introduce her to some chicks that I buy from hatchery, will she raise them? I realize there are no guarantees and I should have a brooderr ready just in case, but is there a good chance a hen will take to the babies? If it helps I'm planning on a flock of Australorps. If a hen will take them how many should I adopt to her? Thank you for your input!
